Blockchain Interoperability

Rollup

A Layer 2 scaling solution that executes transactions off-chain and posts compressed transaction data to the main chain.

Sidechain

A separate blockchain connected to a main chain through a two-way bridge, allowing assets to move between them.

Cross-Chain Bridge

Infrastructure enabling the transfer of assets and data between different blockchain networks.

Interoperability

The ability of different blockchain networks to communicate, share data, and transfer value between each other.

A digital system for recording, sharing, and synchronising data across multiple sites without a central administrator.

The economic design and incentive structures governing a cryptocurrency or token ecosystem.

The base blockchain protocol layer that handles consensus, data availability, and transaction settlement.

A radical change to a blockchain's protocol that makes previously invalid blocks or transactions valid, requiring all nodes to upgrade.

A one-way function producing a fixed-length output that is computationally infeasible to reverse or find collisions for.

A technical standard for non-fungible tokens on the Ethereum blockchain, ensuring each token is unique.

A Layer 2 scaling solution using zero-knowledge proofs to validate off-chain transactions on the main blockchain.

A backward-compatible upgrade to a blockchain protocol where old nodes still recognise new blocks as valid.
